Definitions

  • the present invention relates to a dynamic braking device for a railway vehicle.
  • a dynamic braking device is intended to use the motorization of a vehicle as a generator in order to reduce its speed.
  • the captured energy is then for example dissipated in the form of heat, by means of at least one rheostat.
  • the rheostat is arranged on the roof. For reasons of gain in size, this rheostat is in some cases arranged below an equipment, for example a pantograph.
  • this equipment is then in an area of high heat, which can affect its operation, its reliability and / or its lifetime.
  • the invention is intended to overcome this disadvantage, by providing a dynamic braking device does not affect the roofing equipment of the railway vehicle.
  • the subject of the invention is in particular a dynamic braking device for a railway vehicle comprising a roof provided with at least one piece of equipment, the dynamic braking device comprising at least one rheostat intended to be arranged on the roof of this vehicle.
  • rail and below said equipment characterized in that it comprises a thermal deflector covering the rheostat, having lateral openings on either side of the rheostat in a transverse direction, and a deflection panel arranged above the rheostat, and intended to be arranged below said equipment, the deflection panel being formed to present, in the transverse direction, a width greater than a known width of said equipment in the same transverse direction.
  • the heat deflector discharges hot air laterally, on either side of the equipment above the deflection panel, so that the equipment is not in a hot air flow.
  • the invention therefore allows a compact arrangement of the rheostat and the equipment (generally a pantograph), without harming this equipment.
  • the invention also relates to a railway vehicle, comprising a roof equipped with equipment, characterized in that it comprises a dynamic braking device as defined above, wherein the rheostat is arranged below said equipment.
  • the invention finally relates to a thermal deflector for a dynamic braking device as defined above, intended to cover the rheostat of the dynamic braking device, and having lateral openings on either side of the rheostat in a transverse direction, and a deflection panel intended to be arranged above the rheostat, and intended to be arranged below a railway vehicle equipment, the deflection panel being formed to have, in the transverse direction, a width greater than a known width of said equipment in this same transverse direction.
  • a roof 10 of a railway vehicle comprises a dynamic braking device, designated by the general reference 12.
  • the dynamic braking device 12 conventionally comprises a rheostat 14 for discharging in the form of heat energy recovered by dynamic braking. It should be noted that the dynamic braking device 12 also comprises in a conventional manner all the elements necessary for its operation. These elements will not be described in detail.
  • the rheostat 14 is arranged on the roof 10 of the railway vehicle, below an equipment 16 in a vertical direction Z.
  • the equipment 16 is a pantograph.
  • the pantograph 16 is carried by a support 17, for example formed by a seat carried by four feet.
  • the support 17 makes it possible to support the pantograph 16 above the rheostat 14.
  • the dynamic braking device 12 comprises a thermal deflector 18 covering the rheostat 14. More particularly, the thermal deflector 18 is arranged between the rheostat 14 and the support 17.
  • the thermal deflector 18 shown in more detail on the figure 2 , has front and rear walls 20 perpendicular to a longitudinal direction X (perpendicular to the vertical direction Z), and an upper deflection panel 22, together forming a housing for the rheostat 14.
  • the walls 20 are arranged on both sides. the other of the rheostat 14 in the longitudinal direction X, and the deflection panel 22 is arranged above the rheostat 14 in the vertical direction Z. It should be noted that the deflection panel 22 is arranged under the support 17, therefore under the equipment 16.
  • the thermal deflector 18 comprises lateral openings 24 on either side of the rheostat 14 in a transverse direction Y perpendicular to the longitudinal direction X and to the vertical direction Z.
  • the thermal deflector 18 is without side walls, so that it consists of the walls 20 and the deflection panel 22.
  • the deflection panel 22 is formed to have, in the transverse direction Y, a width greater than a width of said equipment 16 in the same transverse direction Y. In other words, the deflection panel 22 extends laterally beyond of the equipment 16. It will be noted that the equipment 16 intended to overcome the deflection panel 22 is known during the development of the deflection panel 22. The dimensions of the deflection panel 22 will therefore be chosen according to this equipment. predefined. For example, when the equipment 16 is a pantograph, we know the size of the archers of the pantograph, and the width of the deflection panel 22 is chosen according to this known size.
  • the deflection panel 22 extends beyond the front and rear walls 20 in the transverse direction Y.
  • the deflection panel 22 is formed by two inclined side panels 26, so that this deflection panel 22 has a shape of V, whose apex 28 extends in the longitudinal direction X.
  • the side panels 26 extend above a horizontal plane passing through the apex 28.
  • the side panels 26 are inclined upwards from the top 28, and converge towards each other. the other down.
  • each side panel 26 forms, with said horizontal plane, an angle between 0 ° and 15 °, more particularly between 2 ° and 5 °. Indeed, such an angle forms an optimal compromise between a good deflection of heat and a small footprint in the vertical direction Z.
  • thermal deflector 18 makes it possible to deflect the heat evacuated by the rheostat 14 on either side of the equipment 16, so that this equipment 16 is not in the evacuated heat flow.
  • the deflection panel 22 is wider than the equipment 16, and arranged between the rheostat 14 and this equipment 16, it prevents the heat back to the equipment 16, being deflected to the side.
  • the inclination of the panels 26 upwards makes it possible to optimize the flow of the heat flow, so as to avoid a chaotic flow which would involve a risk of return of the heat towards the equipment 16.
  • a angle between 2 and 5 ° allows a good flow flow, while maintaining a reduced vertical space for the deflection panel 22.
  • thermal deflector 18 has openings 24 only laterally, the housing in which is housed the rheostat 14 being obstructed forwards and back by the walls 20. It is thus ensured that the heat flow is deviated on the side only, for maximum protection of the equipment 16.
